FWH reduce the friction / drag of turning the front drive train, less to turn less power needed better MPG. Give them a go, Keep the bits you take off in case you don’t like it.
Some modern 4x4 have automatic ones fitted as standard.

yer gonna have to explain that one to us.

if yer front axle int connected to the injun cause yer in 2wd then yer injun int gort ta turn it.

if yer on about over coming rolling resistance of the diff etc . then thur int much.

and if yer gonna be 4wd ing , and lets fact it that what yer bought it fer, the hassle of remembering to climb out and engage the fookers ( yer might be knee deep in mud) out weights the small advantage yer gonna get by not having to overcome that small amount of rolling resistance produced by the diff etc.

good idea in therory but a load of old bollocks in practice.


if they was that good dint yer think folk that had a huge fleet of series landies would have used them?
 
This topic always has it's fors & againsts!

I think they're pretty pointless. Reckon you'd get more improvement in MPG by making sure your tyres are inflated to the correct pressure, removing the tools you don't use frum the back (which of course you'll bitterly regret if you need them!), closing yer vent flaps & windows & making yer Doris diet or git the bus.

You'd need a helluvan improvement to justify fifty or sixty knicker for a pair so I guess it's a case of if some came up as cheap as deep fried potato slices fit 'em & see. Otherwise save yer cash for a Hi-clone and sum Snake Oil. ;)

When in 2wd the rear axle is the driving force, the front axle just idles, wheels turn and in turn drive all the transmission back to the Gear box.

With FWH fitted the link between the Wheel (Hub) is disconnected and just the wheels turn. The front diff and prop shaft don’t.

With the axles having fully floating bearings the drive shaft sits in a world of its own doing nothing.
Until FWH are engaged.

Try turning it by hand and see how hard it’s to turn.
I am sure there will be other explanations if you do a search.

ffs lad the engine is strong enough to propel a fully laden vehicle at 50-60 mph. do you really think the resistance in turning the diff etc is gonna bother it?

oh and this might surprise yer but in over ten years of working on series landrovers i did manage to find time to turn a few wheels by hand.
do yer think that is down to me eating 3 shredded wheat fer breakfast?
 
ha ha ha ha ha ha ha ha ha
less drag ho ho deee ho

the thing has the aerodynamics of one of me shredded wheat do yer really think stopping the diff from turning is gonna make much difference
 
I think it was Tesco that said every little helps, you can also get your shredded wheat there.
I thought this thread was about FWH not overheating.
